Peeling & Deveining Shrimp
You can buy shrimp that's already peeled and deveined, but you'll pay less for your shrimp if you do it yourself. It takes a little patience and time, but it's not hard.
To de-vein and peel shrimp, use a paring knife to make a shallow slit along the back from the head end to the tail end. Peel the shell back in the way, leaving the tail if desired. Now, look for the black vein that runs along the center of the back. If the vein is there, use your fingers or the tip of the knife to carefully remove and discard it. Removing the vein under running water may be easier for some cooks.
